| proteins that control most chemical changes that occur in an organism. | enzyme |

| process where the mitochondria in the cells break down the food particles and release energy. | cellular respiration |
| type of respiration that uses oxygen to break down glucose molecules into carbon dioxide, water, and ATP | aerobic respiration |
| type of respiration, also called fermentation, that breaks down glucose molecules into carbon dioxide, alcohol, and ATP | anaerobic respiration |
| chemical reaction used by producers, such as green plants, to make food | photosynthesis |
| transport process that uses no energy and moves molecules from where there is more to where there is less until it is equal | passive transport process |
| movement of particles in a liquid or gas from an area where there is more to where there is less | diffusion |
| a special type of diffusion where water moves across a membrane | osmosis |
| movement of a solid into or out of a cell that takes energy | active transport |
